Abstract: Various aspects of the present disclosure provide for methods, apparatus, and computer software for enabling a single media access control (MAC) layer to control a variety of physical (PHY) layers or entities for multiplexing signals corresponding to each of the PHY layers over an air interface. Here, the MAC layer may include a resource manager configured to determine a time-frequency resource allocation within the air interface for communication with one or more subordinate entities utilizing each of the PHY layers. In this way, The MAC entity may provide dynamic control over the allocation of time-frequency resources within a given resource group, which may include transmission time intervals (TTIs) having multiple time scales.

Abstract: Methods, systems, and apparatuses are described for wireless communication at a base station. The base station may transmit a control message to a set of user equipments (UEs) using a directional transmission having a first beamform width. The base station may exchange, according to the control message, data messages with a first UE of the set of UEs using a directional transmission having a second beamform width. The second beamform width may be different from the first beamform width. The base station may exchange, according to the control message, data messages with a second UE of the set of UEs using a directional transmission having a third beamform width. The third beamform width may be different from the first beamform width, the second beamform width, or both.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include identifying a reference number of tones for an overhead channel of a transport block and segmenting the transport block into a code block based at least in part on the reference number of tones for the overhead channel. In some examples, a code block indicator or the reference number of tones may be transmitted on a control channel. Another method may include receiving a code block size indicator associated with a code block of a transport block, decoding the code block based at least in part on the code block size indicator and assembling the transport block based at least in part on the decoded code block. In some examples, the code block size indicator may be received using a control channel.

Abstract: The disclosure relates in some aspects to an energy-aware architecture that supports a low power scheduling mode. For example, a media access control (MAC) architecture for a base station (e.g., an enhanced Node B) and associated access terminals (e.g., UEs) can take the power needs of the access terminals into account when scheduling the access terminals. In some aspects, an access terminal may support a particular frame structure for a low power mode. Accordingly, scheduling of the access terminal may include use of the particular frame structure during low power mode.

Abstract: The disclosure relates in some aspects to techniques for improved channel estimation. For example, a device can specify a pilot structure where pilot density differs over time. As another example, a device can indicate that a pilot from a prior transmission time interval (TTI) can be used for channel estimation. As another example, a device can employ frequency domain physical resource block (PRB) bundling with the bundling information signaling. As yet another example, a device can use an adjustable traffic-to-pilot ratio (TPR) for throughput optimization. Other aspects, embodiments, and features are also discussed and claimed.

Abstract: Methods, systems, and devices are described for wireless communication at a UE. A base station may select a hybrid pilot configuration including a relatively sparse periodic pilot and a dense pilot embedded in one or more symbols of a low latency burst. A user equipment (UE) may generate a long term statistical average channel estimate based on the periodic pilot and an instantaneous channel estimate (e.g., for demodulation) based on the dense pilot embedded in the low latency burst. The UE may refine the instantaneous channel estimate by converting a control channel embedded with the burst. In some instances, the base station may embed the dense pilots in the first symbol of a burst and transmit subsequent low latency symbols with a reduced density pilot (or without pilot tones).

Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.
